We've been working on another code search engine for open-source: https://sourcegraph.com/. Our approach is a little different -- we parse and index things at a programming language level. This has the benefit of being able to list usage examples of a function or jump to a definition (i.e., smart IDE-like behavior). Obviously, one drawback is having to implement language-specific support; right now Sourcegraph just supports Python, Javascript (node.js) and Go.
Would love to hear people's feedback on either approach!
